How does bump app works?

Bump was a mobile app that allowed users to exchange contact information and files by physically bumping their smartphones together. Users would open the app, select the information they wanted to share, and then tap their devices together, triggering the transfer via Bluetooth. The app simplified the process of sharing details like phone numbers, photos, and social media profiles without the need for manual input. However, the service was discontinued in 2014, and users have since turned to other methods for file sharing and contact exchange.
